Children's discomfort may vary among different treatments for initial approximal caries lesions: preliminary findings of a randomized controlled clinical trial

Postoperative instructions for silver diamine fluoride therapy: A scoping review of current evidence and practice

OBJECTIVES

Silver diamine fluoride (SDF) has gained popularity in dentistry as an anti-hypersensitive and anti-caries agent. This study aims to review the postoperative instructions for SDF therapy and examine the evidence supporting these instructions in treating dentine hypersensitivity and caries control.

DATA AND SOURCES

Two independent reviewers searched three electronic databases (EMBASE, PubMed, and Web of Science) to identify clinical studies that used SDF to treat dentine hypersensitivity and dental caries. Additionally, they searched Google Chrome for information from manufacturers, the department of health, national dental organisations, authoritative dental organisations, and universities regarding SDF therapy for these conditions. Data on postoperative instructions were extracted, and their impact on the treatment of dentine hypersensitivity and caries control was investigated.

STUDY SELECTION

This review included 74 clinical studies, 11 sets of instructions from SDF manufacturers, and six recommendations from national dental organisations, departments of health and universities. Amongst the included records, 50 clinical studies, two manufacturers, and one department of health mentioned postoperative instructions for SDF therapy. The recommendations varied, from suggesting no specific instructions, immediate rinsing, refraining from eating or drinking for 30 to 60 min, and even avoiding brushing until the next day after SDF therapy. Notably, no clinical studies reported the effects of these postoperative instructions on the SDF treatment of dentine hypersensitivity or dental caries.

CONCLUSIONS

This scoping review highlights the presence of inconsistent postoperative instructions for SDF therapy in the treatment of dentine hypersensitivity and caries control. Furthermore, there is a lack of evidence supporting the effectiveness of these instructions.

CLINICAL SIGNIFICANCE

No evidence supports the postoperative instructions for SDF therapy for managing dentine hypersensitivity and dental caries. Studies are necessary to provide guidance for clinicians using SDF in their clinical practice.

The Impact of Minimal Intervention Dentistry on Patient-Reported and Observation-Based Outcomes in the Pediatric Population: A Systematic Review and Meta-Analysis

This review aimed to systematically investigate the effect of minimal intervention dentistry on patient-reported and observation-based outcomes of anxiety, pain and patient cooperation in the pediatric population. Microinvasive treatments (MITs) were compared to conventional treatments, home-based and professionally applied non-invasive treatments (NITs), and between MITs. Two reviewers independently screened studies from four electronic databases, extracted data, assessed the risk of bias and certainty of evidence with the GRADE approach. Ultimately, 26 studies were included for qualitative synthesis, with the data from 12 studies being incorporated into the meta-analysis. No statistically significantly differences in terms of anxiety were noted between MITs and conventional treatments, or between MITs from the meta-analyses. The treatment durations of MITs were not necessarily shorter than conventional treatments but varied with the use of local anesthesia, behavioral and clinical approach, and other confounding factors. The certainties of evidence were deemed low due to high risk of bias of the included studies. NITs evoked less anxiety and pain compared to MITs. Minimal intervention dentistry is an alternative treatment to manage dental caries among children and does not arouse different levels of dental anxiety and pain compared to other treatment modalities. However, further well-designed studies are required to draw an evidence-based conclusion.

Management of Hypoplastic or Hypomineralized Defects with Resin Infiltration at Pediatric Ages: Systematic Review

Hypoplastic or hypomineralized enamel defects represent a recurrent reason for consultation within the pediatric population, causing great discomfort due to their aesthetic appearance, as well as their functional limitations. Current conservative dentistry requires minimally invasive treatments in order to treat such defects and provide successful, definitive solutions. A systematic review of the literature has been carried out in accordance with the PRISMA recommendations. A search was carried out in the PubMed, Scopus, SciELO and Web of Science databases, completed with a manual search. The following variables were extracted from the selected studies: author, year, publication journal, type of study, sample, age of the participants and the materials used for its development. From the initial electronic search of the four databases, 282 articles were identified: 34 from PubMed, 240 from Scopus, 0 from SciELO and 8 from Web of Science. After eliminating duplicate articles, a total of 225 remained. After reading the title and abstract, 158 articles were eliminated, leaving 68. Upon reading the full text, the remaining studies were eliminated for not answering the research question or the inclusion criteria, leaving a total of 13 articles. Finally, 12 articles were used to carry out the systematic review. Treatments performed to date with the ICON™ system in pediatric patients have shown good results after their application. Since the variability of diagnostic methods has been observed, new diagnostic and assessment protocols should be created after treatment to objectify their effect on hypoplastic or hypomineralized enamel defects. In the same way, it has been described that treatment provides better results if combined with other opalustre-type or remineralizing materials. This review is registered in PROSPERO with the number CRD42021288738.

A retrospective clinical study on the resin infiltration of proximal caries lesions: the operator's effect

Purpose

This retrospective university-based study investigated the effect of operators’ training and previous experience on the success of resin infiltration (RI) in arresting proximal non-cavitated caries lesions in primary and permanent teeth.

Methods

Information was collected regarding RI of proximal non-cavitated caries lesions in primary and permanent teeth with a follow-up period up to 32 months. Factors investigated were: operators’ clinical experience and training, patient’s age, tooth, arch, mouth-side, surface treated, tooth separation, and baseline lesion depth. Kaplan–Meier survival and Cox regression analysis with shared frailty were used (α = 5%).

Results

A total of 130 proximal surfaces treated on 115 teeth of 43 children (11 ± 4.4 years) were evaluated. Survival of RI was 46% up to 32 months. Lesions treated by non-trained dentists were more likely-to-present progression than those performed by non-trained dental students under supervision (HR 2.41, 95% CI: 1.00–5.80); conversely, no difference was found between non-trained dental students under supervision and trained dentists (HR 0.52, 95% CI: 0.16–1.70). Additionally, dentin lesions were 59% more-likely-to-present progression than enamel lesions (HR 0.41, 95% CI: 0.17–0.99).

Conclusion

The operator’s experience and training could influence the success of RI on proximal non-cavitated caries lesions and it should be taken into consideration when choosing this treatment modality.

Child discomfort and parental acceptability of silver diamine fluoride and alternative restorative treatment: A randomized controlled clinical trial

OBJECTIVES

To compare pain perception of young children treated with SDF and ART, as well as their parents' acceptability of both modalities.

METHODS

Eighty, 3 to 8-years old children, having at least one deciduous asymptomatic tooth with active caries, as defined by the ICDAS II scores 4, 5, 6 were randomly assigned into two groups; SDF for caries arresting in the test group, and ART for caries removal in the control group. Pain perception was assessed using Sound, Eye, Motor scale (SEM), whereas parental acceptability was assessed using a self-administered questionnaire.

RESULTS

Patients treated with SDF reported significantly less discomfort and pain compared to the ART group, with a mean SEM of 3.70 ± 1.47 and 6.18 ± 3.06, respectively (p < 0.001). A significantly higher mean parental acceptability score was detected for SDF treatment (31.85 ± 2.30) than ART treatment (26.75 ± 3.60), p < 0.001, with regard to the treatment duration, child comfortability and quality of treatment (p < 0.001). The only dimension showing more satisfaction for the ART treatment was esthetics of anterior teeth (p= 0.01).

CONCLUSIONS

Parental acceptability was higher for the SDF caries treatment of primary teeth compared to ART treatment, especially in relation to the shorter intervention time, child comfortability and acceptance as well as quality of treatment.

CLINICAL SIGNIFICANCE

The shorter average time needed and the ease of application of SDF on cavitated primary lesions, in addition to parental acceptability, place SDF in an advantageous position over the ART on clinical level.

Parental Acceptance for the Use of Silver Diamine Fluoride on Their Special Health Care-Needs Child's Primary and Permanent Teeth

Purpose

The effectiveness and simplicity of the procedure and the low expense are the main advantages of silver diamine fluoride (SDF). It is useful for controlling caries in challenging patients such as those with special health care needs (SHCN). First aim of this study was to assess parents’ acceptance towards using SDF in SHCN children in their primary and permanent teeth. Second aim was to determine the factors that influence parents’ decisions toward dental treatment options.

Patients and Methods

This descriptive cross-sectional study included the parents of SHCN children aged 12 years old and younger who were actively seen in pediatric dentistry clinic at King Fahad Medical City (KFMC) and were receiving dental treatment. A previously developed and tested questionnaire was used. The surveyors received training about the questionnaire and participants’ consent was obtained before enrolling in the survey. The statistical significance level was set at P<0.05.

Results

Two hundred twelve participants completed the study questionnaire. Parents had a higher acceptance of SDF use regardless of the tooth location and type when their child had a positive history of pain and/or inflammation (P=0.019). In addition, parents had higher acceptance of SDF staining in primary teeth compared to permanent teeth (P=0.006). Moreover, the acceptance of SDF staining was higher in posterior teeth compared to anterior teeth in both primary and permanent dentition (P<0.001).

Conclusion

Parental acceptance of SDF was higher for primary compared to permanent teeth and posterior compared to anterior teeth in both dentitions, as well as for those with a positive history of dental pain and/or inflammation.

Caries arrest effectiveness of silver diamine fluoride compared to alternative restorative technique: randomized clinical trial

OBJECTIVE

This RCT study assessed and compared the effect of a biannual application of 38% silver diamine fluoride (SDF) with alternative restorative technique (ART) on arresting caries in primary dentition.

METHODS

The RCT was conducted over a period of 12 months and included 79 healthy children (237 primary teeth), aged 3-8 years, selected from the University Pediatric Dentistry outpatient clinics, with at least one primary asymptomatic tooth with active dentinal occlusal/labial lesions. Children were randomly assigned to SDF application or ART treatment. Visual and tactile examinations were used after 6 and 12 months to assess the activity of the carious lesions using the ICDAS II.

RESULTS

At 6- and 12-month-evaluation periods, no statistically significant differences in lesions arrest were found between SDF and ART groups (P = 1.000). Considering the frequency of arrested caries between the test groups at 6 and 12 months, no significant differences were observed between anterior and posterior lesions, as well as between the maxillary and mandibular lesions. When comparing the working time for the two treatments, the median time for those treated with SDF was 3.3 min, compared to 14.4 min for ART and was statistically significant (P < 0.0001).

CONCLUSION

Both SDF and ART are, indeed, effective for arresting caries. However, the chair-time management required for SDF is significantly shorter compared to ART. Taking into consideration the present evidence, the best decision regarding disease management and application of SDF or ART is to be made by the dentist and the patient/parent, recognizing individuals' differences and preferences.

Efficacy of 30% silver diamine fluoride compared to atraumatic restorative treatment on dentine caries arrestment in primary molars of preschool children: A 12-months parallel randomized controlled clinical trial

OBJECTIVES

This clinical trial investigated the efficacy of silver diamine fluoride (SDF) in arresting dentine caries in primary molars of preschoolers. Time required for treatment, adverse effects, parental aesthetic perception, anxiety and oral health related to quality of life (OHRQoL) was evaluated.

MATERIALS AND METHODS

Children, 2-5 years old, with active dentine caries lesions on the occlusal surface of primary molars were randomly allocated to test group (SDF) or control group (atraumatic restorative treatment/ART). The dmf-t/DMF-T and ICDAS indexes determined the presence of caries and activity. The main outcome after 3, 6 and 12-month follow-up was assessed by a blind examiner. The time required to perform the treatments was recorded and a facial image scale was applied to assess anxiety before and after treatment. Adverse events and aesthetic perception were assessed through questions addressed to caregivers; and the OHRQoL through the B-ECOHIS questionnaire.

RESULTS

In 68 patients that were randomized, the mean number of treated teeth per child was 2.42(1.04) and 2.09(1.18) in the SDF and ART groups (p = 0.074), respectively. The mean difference of arrested lesions between the groups after 12 months was -0,07(0.05; - 0.17-0.30). The time required to treat with SDF was lower than the ART (p < 0.001). There was no difference in the percentage of adverse events + aesthetic perception (p = 0.709), and the change in anxiety (p = 0.155). There was a less impact in OHRQoL after ART treatment, but only when the parents' distress subscale was considered (p = 0.012).

CONCLUSION

SDF requires much less chair-time and have similar results as ART in arresting caries lesion, anxiety, adverse effects, aesthetic perception and quality of life.

Parental acceptance of the utilization of silver diamine fluoride on their child's primary and permanent teeth

Purpose: Silver diamine fluoride (SDF) is an effective caries control agent. The aim of our study was to investigate the parental acceptance of the utilization of SDF on their child's primary and permanent teeth and to determine the factors that influence their decision-making. Patients and methods: This descriptive cross-sectional study included parents of healthy children aged 12 years and younger and currently receiving dental treatment. The interview questionnaire was conducted and pre-tested for face and content validity. The trained interviewing dentists showed colored pictures of primary and permanent teeth before and after receiving SDF treatment. The statistical significance was set at P<0.05. Results: A total of 104 parents were included in the study. The mean parental rating of treatment acceptability of the staining associated with SDF was 3.9±1.95. The plurality considered the staining caused by SDF treatment strongly not acceptable 46 (43.4%). Parental acceptance of SDF treatment was significantly affected by the location and type of teeth. Parents showed significantly higher acceptance of SDF treatment on their child's primary compared to permanent teeth and posterior compared to anterior in both dentitions (P<0.001). In addition, parents of children with a history of uncooperative behavior during previous dental treatment were significantly more accepting of SDF treatment regardless of the type and location of the teeth. Conclusion: Parental acceptance of SDF increased for primary compared to permanent teeth, on anterior compared to posterior teeth in both dentitions and for uncooperative children.

Aesthetic perception, acceptability and satisfaction in the treatment of caries lesions with silver diamine fluoride: A scoping review

BACKGROUND

Silver diamine fluoride (SDF) causes dental black staining after its application.

AIM

Evaluate the aesthetic perception, acceptability, and/or satisfaction of patients, parents, and professionals to the treatment of caries lesions with SDF through a scoping review.

DESIGN

A search was performed in seven databases and two key journals with no language or date restrictions. Studies that evaluated the aesthetic perception, satisfaction, and/or acceptability of patients, parents, and professionals to the treatment of carious lesions with SDF were considered eligible.

RESULTS

From a total of 1177 articles, 10 studies were full text assessed for eligibility, with nine included in this scoping review. In general, the studies varied by population, study design, and methodologic evaluation. The type of tooth (anterior or posterior), family income, parental schooling, ethnicity, and need for advanced behaviour control methods were factors that influenced the results. The acceptability level increased as the child required more advanced methods of behaviour guidance. In general, the pigmentation caused by SDF did not interfere with the parents' acceptability of the treatment; however, professionals believe that this could have influence. Regarding satisfaction, pigmentation did not influence parental satisfaction.

CONCLUSION

Parents were satisfied with and found SDF acceptable, whereas professionals did not.

Pediatric Dentists' Silver Diamine Fluoride Education, Knowledge, Attitudes, and Professional Behavior: A National Survey

Silver diamine fluoride (SDF) is an inexpensive treatment for arresting cavitated carious lesions in a minimally invasive way. The aims of this study were to assess U.S. pediatric dentists' SDF educational experiences, knowledge, attitudes, and professional behavior and to explore the relationships among these constructs. For the cross-sectional survey, recruitment emails were sent to all 6,230 members of the American Academy of Pediatric Dentistry (AAPD). Responses were received from 582 members (response rate 9.34%). In the results, only 3% of the respondents reported having been well/very well educated about SDF in classroom settings in dental school and only 9.6% during their residency. Positive SDF professional development was reported frequently (education through publications 53%, online resources 41%, continuing education courses 38%). The majority knew much/very much about what SDF is used for in dentistry (77%), about treating caries in pediatric patients (80%), and which problems SDF use can have (62%). Their SDF attitudes were positive: SDF use was considered a good treatment alternative for restorations in children with behavioral problems (85%) and for patients who were medically fragile (85%) or had severe dental anxiety (81%). Among the respondents, 31% used SDF often/very often to arrest carious lesions in primary teeth, and 87% expected increased future SDF use. The more SDF professional education the respondents had, the more self-reported knowledge they had (r=0.52; p<0.001), the more positive their SDF-related attitudes (r=0.25; p<0.001), and the more likely they were to use SDF (r=0.37; p<0.001). These results suggest that expanded education about the proper use, benefits, and limitations of SDF is needed and is likely to increase pediatric dentists' SDF utilization.

Efficacy of resin infiltration of proximal caries in primary molars: 1-year follow-up of a split-mouth randomized controlled clinical trial

OBJECTIVE

The main purpose of this split month, randomized, controlled clinical trial was evaluate the efficacy of caries infiltration in controlling the progression of non-cavitated proximal lesions in primary molars. Anxiety and time required for the caries infiltration was also evaluated.

MATERIALS AND METHODS

Fifty healthy children, 5 to 9 years, presenting two primary molars with proximal caries lesions (1/2 of the enamel or outer 1/3 of dentin), were included. Lesions were randomly allocated to the test group (fluoridated toothpaste + flossing + infiltration) or to the control group (fluoridated toothpaste + flossing). Caries risk was based on the Cariogram model. The main outcome after 1-year radiographic follow up was assessed by an independent blinded examiner A facial image scale (FIS) was applied to assess dental anxiety and time required to perform the infiltration was recorded.

RESULTS

Of the sample, 92.9% corresponded to high or medium caries risk. In 42 patients (1-year follow up), caries progression was observed in 11.9% (5/42) of the test lesions compared with 33.3% (14/42) of the control lesions (p < 0.05). Five control and three test lesions progressed to the middle 1/3 of dentin and were restored. No side effects were observed. Anxiety was both low before and after the treatment, and mean time required for the infiltration was 11.29 min (± 1.16 min).

CONCLUSIONS

Caries infiltration of proximal caries lesions in primary molars is significantly more efficacious than standard therapy alone (fluoride toothpaste + flossing).

CLINICAL RELEVANCE

Caries infiltration is an applicable and well-accepted method be used in children, representing a promising micro-invasive approach.

Effect and acceptance of silver diamine fluoride treatment on dental caries in primary teeth

OBJECTIVES

Silver diamine fluoride (SDF) treatment has been identified as a potential solution to address the dental public health issues of untreated dental caries and insufficient access to care. The current study assessed the effectiveness of 38 percent SDF in arresting active dental caries lesions and in reducing or preventing associated dental pain and infections in young, at-risk children.

METHODS

We enrolled 32 children aged 2-5 years with 118 active caries lesions in primary teeth from a community dental clinic in Oregon. After baseline examinations, carious lesions were treated with 1-2 applications of 38 percent SDF. Children were re-evaluated at 3-week and 3-month recalls to assess color and consistency changes in lesions (soft/hard). Parents were interviewed regarding symptoms of pain or infection and were surveyed regarding subjective feelings about SDF.

RESULTS

Of 102 lesions (16 excluded from analyses), 100 were found to be arrested at first recall and all at second recall. The duration of SDF application was not associated with arrest of decay (P = 0.68). No incidence of pain or infection of an SDF-treated tooth was recorded. Parental impression of ease of application, taste, and esthetics was favorable.

CONCLUSIONS

Our results suggested SDF was effective in arresting active caries lesions in primary teeth in young children and was well accepted by parents. SDF offers an easy and highly efficient nonsurgical alternative treatment to traditional restorative dental treatment in young children, and it has great potential to aid the dental public health community to address dental caries in at-risk populations.

Resin Infiltration of Caries in Primary Molars in a Community Setting: 24-Month Randomized Controlled Trial Findings

This study aimed to assess whether resin infiltration of primary molar proximal lesions is more effective than noninvasive measures in radiographically controlling carious lesion progression into the dentin. A split-mouth randomized controlled trial included 90 children, each with 2 proximal lesions confined to the inner half of the enamel or ≤0.5 mm into the dentin. For each child, lesions were randomly allocated to test (infiltration: DMG Icon preproduct and fluoride varnish) or control (fluoride varnish) status. The primary outcome measure was 24-mo radiographic lesion progression. Placement of a restoration during the study period was counted as lesion progression. Proportions of teeth with progressed lesions were compared using the McNemar test. Children also reported on the treatment's acceptability to them. Children (46% female) ranged in age from 6 to 9 y. Their mean number of decayed, missing, and filled teeth (d₃mft) was 2.8 (SD 2.6). At baseline, 58% and 42% of children were at moderate and low risk, respectively. Test and control lesions presented with similar radiographic lesions at baseline. At the 24-mo follow-up, 6 children had moved and 30 teeth had exfoliated. In the test and control groups, 15 of 66 lesions (22.7%) and 30 of 69 lesions (43.5%) had progressed, respectively (P < 0.05). The 2-y therapeutic effect (based on pairwise radiographic readings) of infiltration over fluoride varnish was 20.8% (95% confidence interval, 10.6%-30.2%). Nearly all children (96.7%) had enjoyed their visit to the clinic, and more than two-thirds (72.2%) were not worried about returning for treatment. Infiltration is more efficacious than fluoride varnish for controlling carious lesion progression in proximal lesions in primary molars, and most children find the treatment acceptable (Australian New Zealand Clinical Trials Registry ANZCTR.org.au ACTRN12611000827932). Knowledge Transfer Statement: These study findings can help clinicians decide which caries management approach they wish to use to prevent progression of proximal lesions in primary molars. With consideration of cost and patient preference, this information could lead to more appropriate therapeutic decisions.
